Headspace SPME Used in Chlorophenols Analysis

Researchers from National Chung Hsing University (Taichung, Taiwan) analyzed four chlorophenols in aqueous samples using purge-assisted headspace solid-phase microextraction (SPME) followed by gas chromatography–mass spectrometry (GC–MS). They investigated various extraction parameters, including extraction temperature, purge gas flow rate, and extraction time. The compounds analyzed were 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol, and pentachlorophenol. The researchers successfully used the technique to analyzed the chlorophenols in landfill leachate.
